+execute_cmd.c
+	- execute_pipeline: if we don't call append_process, call

+jobs.c

+	- {set_job_control,initialize_job_control}: set running_in_background
+	  to 1 if terminal pgrp != shell pgrp
+	- {stop_pipeline,make_child,wait_for}: if we are running in the
+	  background, don't mess with the terminal's process group; assume that
